LazyInitializationException with OpenEntityManagerInViewFilter

[danielfarkas]

Resolved !


Migrated to the WebLogic 11, and changed the EclipseLink persistence provider to prove that support for 2.1 Lazy and transactions outside the EJB container.
Minimum configuration, good.
following configuration:

web.xml

<filter>
		<filter-name>openEntityManagerInViewFilter</filter-name>
		<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>openEntityManagerInViewFilter</filter-name>
		<url-pattern>*.do</url-pattern>
	</filter-mapping>
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:org/springmvc/resources/spring-context.xml</param-value>
	</context-param>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<servlet>
		<servlet-name>springmvcdispatcherservlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:org/springmvc/resources/spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>springmvcdispatcherservlet</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

persistence.xml

<persistence-unit name="EJBPROJECT">
		<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
		<jta-data-source>jdbc/mySQL</jta-data-source>
		<class>org.ejbproject.entitys.Entidade</class>
		<class>org.ejbproject.entitys.Estado</class>
		<class>org.ejbproject.entitys.Cidade</class>
		<exclude-unlisted-classes>true</exclude-unlisted-classes>
		<properties>			
			<property name="show_sql" value="true" />
		</properties>
	</persistence-unit>

spring-context.xml

<context:load-time-weaver
		weaver-class="org.springframework.instrument.classloading.weblogic.WebLogicLoadTimeWeaver" />

	<bean id="transactionManager"
		class="org.springframework.transaction.jta.JtaTransactionManager" />

	<bean id="entityManagerFactory"
		class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
		<property name="persistenceUnitName" value="EJBPROJECT" />
		<property name="jpaVendorAdapter">
			<bean id="jpaAdapter"
				class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter">
				<property name="databasePlatform"
					value="org.eclipse.persistence.platform.database.MySQLPlatform" />
				<property name="showSql" value="true" />
			</bean>
		</property>
	</bean>

spring-mvc.xml

 <tx:annotation-driven />

	<tx:jta-transaction-manager />

	<context:component-scan base-package="org.springmvc.spring" />

	<context:annotation-config />

	<mvc:annotation-driven />

	<mvc:default-servlet-handler />

The Lazy collections open in view, and any change in the Spring @Service layer bean annotated with @Transaction instantly reflected in the database.

The web module there is nothing persistence, everything is in EJB.

JBoss 5 or 6 is J2SE server, not a JEE server.

Tanks.
